Raven Engineered Films has issued a new technical paper: Advanced Geomembrane Technology for Enhanced Protection of EPS Geofoam in Transportation Systems. The publication is part of the company’s technical library and openly available resources for the geosynthetics and civil engineering fields. DOWNLOAD A COPY IN PDF EPS geofoam samples were protected with various geomembrane types and submerged for up to 160 days...

Porous pavement solutions have drawn considerable interest in communities for the green engineering benefits they provide. Porous pavements can greatly reduce stormwater runoff by enabling a high infiltration or percolation rate of water into underlying soils. The permeability of these systems can also trap suspended solids, thus filtering them out of any residual runoff so water that is shed...

The Presto Geosystems team continues to grow. The company has announced that it is adding a Business Development Manager for a technical sales position in North America. BUSINESS DEVELOPMENT MANAGER The ideal Business Development Manager candidate will be a dynamic leader with success developing distribution networks and overseeing territory projects, promoting technical construction solutions to engineers/architects, creating strong direct customer relationships, and a...

Oregon State University’s Dr. Ben Leshchinsky, P.E. and the University of Kansas’s Dr. Jin Han, P.E. recently combined their wealth of geosynthetics knowledge in a track ballast research study. Specifically, they evaluated the performance of a high-density polyethylene geocellular system (HDPE GEOWEB® from Presto Geosystems) in a railway base stabilization system. The rigorous track testing quantified the beneficial impact of reinforcing...

A portion of a railway track in Fort Lauderdale, Florida had been a high maintenance area for many years due to the impact loads from rail cars transitioning off of a concrete bridge abutment onto ballasted concrete ties. The ties were located over soft subgrade, which had exhibited a history of pumping. The rail operator, Florida East Coast Railway,...

Porous pavement solutions have drawn considerable interest in communities for the green engineering benefits they provide. Grass and gravel porous pavers can greatly reduce stormwater runoff by enabling a high infiltration or percolation rate of water into underlying soils. The permeability of these systems can also trap suspended solids, thus filtering them out of any residual runoff so water...

In late 2017, construction began on a multimodal transportation, industrial, and logistics center in Bolbasovo, which is located in the Orsha region of Belarus. The 230-ha site will function as the linchpin in a “new silk road” between China and Europe. The area is supported by convenient access to railways, an airport, and the intersection of major west-east and north-south...

Pavement durability is always of concern in roadway projects, for safety, cost control, and responsible future planning. Geosynthetics offer a number of solutions to improve roadway performance, including prevention of reflective cracking. Machina-TST has made a strong impression in the road-building market with products such as ASPHALTEX (a PET, bitumen-coated geogrid) and DUALTEX (a geogrids-geotextile composite). Now, the company has engineered...

The M6 Highway is one of Belarus’s 14 major motorways. It provides essential connection from the capital of Minsk to Grodno near Poland and the Bruzgi border crossing point. In the larger European roadway network, the M6 is affiliated with the E28 road. The highway system in Belarus has been undergoing substantial expansion. As part of the M6 highway...

Machina-TST has grown quickly behind lines of geotextiles, geogrids, geocomposites, and turf reinforcement mats. Now, it’s turning its manufacturing technical knowledge to erosion control applications with the expanded release of its needlepunched biomat, Linotex Eco. The organic mat is engineered for the rapid vegetation development and protection of soil from surface erosion processes. The product construction enables a durable grass cover to...
